Choose an EMT two-hole strap by matching its stated trade size to the conduit, then verify the strap’s dimensions, material, finish, mounting-hole layout, and applicable compliance documentation. A strap that looks close in size may not fit securely, and a product described as “UL 2239” should be supported by documentation applicable to the exact product being quoted. Before ordering, confirm the installation conditions and project requirements with the responsible installer or engineer.
This guide helps contractors, distributors, and purchasing teams compare options and prepare a clear product inquiry. It explains how EMT trade size relates to strap selection, what specifications to check, and what information to request from a supplier. As product construction and certification status can vary, treat supplier documents—not a generic product description—as the basis for approval.
This guide is for buyers sourcing EMT two-hole straps for electrical conduit projects, including electrical contractors, wholesalers, OEM purchasing teams, and project procurement staff. It is also useful when comparing quotations that use different descriptions for seemingly similar fittings. If a project specification names a particular standard, finish, or manufacturer requirement, use that document as the controlling reference.
An EMT two-hole strap is a formed fitting used to hold electrical metallic tubing against a mounting surface. Its two mounting holes allow the installer to fasten the strap at two points, while the curved section fits around the conduit. The strap supports conduit along a route; it does not replace connectors, couplings, or other fittings that perform separate functions.
The “two-hole” description refers to the mounting arrangement, while the EMT trade size identifies the intended conduit size. These details should be treated separately in a purchase specification. A correct trade-size match is essential, but the project may also require specific hole spacing, material, coating, or listing documentation.
EMT is ordered by nominal trade size, not by measuring the strap opening or by using the conduit’s outside diameter as its order name. Common EMT trade sizes include 1/2 in, 3/4 in, 1 in, 1-1/4 in, 1-1/2 in, and 2 in. These are nominal size designations; the actual conduit outside diameter differs from the trade-size number.
For reference, commonly specified EMT outside diameters are approximately 0.706 in for 1/2-in EMT, 0.922 in for 3/4-in EMT, and 1.163 in for 1-in EMT. Confirm dimensions against the applicable conduit specification and project documents before using them for fit evaluation. Do not assume that a strap intended for another conduit type or a similarly named size will fit EMT.
Ask for the product drawing or dimensional specification when fit or mounting layout matters. Review the strap’s inside profile, overall width, material thickness, hole diameter, and center-to-center hole spacing. These details help confirm compatibility with the conduit, fasteners, and mounting surface.
Also verify whether the quoted item is a standard two-hole strap or a variation with a different shape, coating, or mounting pattern. If a project requires a particular fastener, substrate, or clearance, share those requirements with the supplier. A size label alone does not establish that every installation detail is suitable.
Straps may be offered in different metals and finishes, depending on the supplier and product range. Compare the material and surface treatment with the installation environment, including exposure to moisture, chemicals, or other corrosive conditions. Where dissimilar metals may contact one another, have the design or installation team assess compatibility for the specific environment.

For indoor, outdoor, or industrial applications, do not select a finish based only on appearance. Request the material description and finish details, and check them against the project specification. If the installation is in a corrosive or otherwise demanding location, obtain project-specific guidance rather than assuming that a general-purpose finish is adequate.
The presence of “UL 2239” in a product title or quotation is not, by itself, enough to confirm the status of a particular strap. Ask the supplier for documentation that identifies the product and supports the stated compliance claim. Check that the documented manufacturer, product description, size, and configuration correspond to the item being purchased.
Do not infer that every size, material, finish, or variation in a product family has the same status. If approval is required for a project, confirm the documentation and acceptance criteria with the authority responsible for review. When a specification uses a particular standard or listing requirement, request written confirmation for the exact SKU or configuration under consideration.
Price comparisons are most useful when quotations cover the same size, material, finish, documentation, and packaging requirements. A lower unit price may not represent the same scope if one offer excludes a specified finish or required documents. Ask suppliers to identify assumptions and exclusions in writing.
Minimum order quantities and lead times depend on the supplier, product configuration, stock position, and order quantity. Rather than relying on a general estimate, request a current quotation that states the MOQ, available quantity, expected lead time, packaging details, and shipping basis. For a time-sensitive project, confirm the schedule before placing the order.
Before approving a supplier, confirm that its quotation clearly identifies the product, EMT trade size, material, finish, and order quantity. Ask whether dimensional drawings and compliance documents are available for review. Also establish the MOQ, lead time, packaging method, shipping terms, and process for confirming any requested customization.
For buyers working with SIOSAN, share the target size, required material and finish, project conditions, estimated quantity, and documentation requirements. We can use those details to review the inquiry and clarify which product information or commercial terms need confirmation. Product availability, customization, and compliance documentation should be verified for the specific item before purchase.
To select an EMT two-hole strap, start with the conduit’s trade size, then confirm the strap’s dimensions, material, finish, mounting layout, and project-specific compliance requirements. A “UL 2239” description should be verified with documentation that matches the exact product being quoted. This approach reduces the risk of ordering a strap that does not fit or does not meet the project’s stated requirements.
Your next step is to prepare a specification with the EMT size, installation environment, preferred material and finish, quantity, and documentation needs. Send it to SIOSAN for a product inquiry or quotation, and request confirmation of the relevant drawings, compliance information, MOQ, and delivery schedule before approving the order.
